Well I have now but 500 miles on it since I got it out of the shop. It was running great and then it seemed to run a little rough. I had the shade tree mechanic look at it and he put some Seafoam that I had heard some people on the board talk about. WOW.. !!!! One mile down the road and it was PURRING again.. How many of you use this stuff and how often can you use it? It seems to be a MIRACLE!!
 
Seafoam is great stuff. How did you use it? Gas tank, intake or oil?
 
I'm thinking gas since it took a mile for it to take effect (intake would have worked quicker oil slower iirc)
 
My gosh I love seafoam. My buddies and I use it on our cars everynow and again. Simply amazing.
 
Mr. MATTW,

I used it recently in my bike and it seemed to make a difference, not that it was running bad before, but now it's smoother and a little quicker when I twist the throttle. I plan to dump a half a bottle or so in a tank of gas a couple times a year, just for maintenance. Some folks use it more often.

Thank you for your indulgence,

Yes, it is great stuff. I used it to bring my 400 back to life. At first I was getting some dismal compression numbers and it looked like I might have to pull the motor apart for a rebuild. A friend suggested Sea Foam so I put some in the gas and some in the oil and voila - that thing runs like a champ now at the compression is 145psi in both cylinders. I think in my case the main problem was a stuck piston ring.

I've sworn by it for years! Even now that my bike is running pretty well I'll still treat a tank about every 3 months at regular strength to keep the gremlins at bay.
 
As far as additives go, Seafoam is about the only thing you should use in a motorcycle engine. It is a fully petroleum based product and reacts well with gas and oil. The only caveat i have heard mentioned is that it shouldn't be used in the motorcycle oil for any length of time as it will breakdown sludge deposits in the upper engine which could cause crap to end up in the transmission/ clutch and it thins out the oil itself. With a new to me bike, I run a few ounces in the first fresh oil change for that purpose ( grunge removal) and change it after a few hundred miles.

You can't over use it in the gas but you only need a few ounces to a tank full. A full can and you'll be puttting out a smokescreen for quite a while.

Good stuff and an easy way to do a quick carb tuneup.

Cheers,
Spyug.
 
I use Berrymans B-12. It works good also. I have a big can for dipping and a small can for the twice a year valve, piston, fuel tank and carb cleaning. I just drop a couple of cap fulls in the tank. Chevron gas will also keep your innards clean.

I put it straight in the tank... I think I have a new friend in the garage....seafoam!! LOL
 
So this thread just inspired me to go out and seafoam my 650.....
It was goin' well, put 1/4 can in the oil and 1/3 can in the tank...
started to rev, seafoam started to smoke, everything was going well then woosh - oil POORED out the back of the motor! HOLY SHAT!
I assume the oil was just overfilled, I don't know, I'm scared to go inspect her.
 
Mr. Euclid,

That's a little disconcerting, to say the least. When I used SeaFoam in my tank, it didn't smoke at all. Use about one ounce per gallon of gas for maintenance, two ounces per gallon for a good cleaning. I've never used it in my oil. But perhaps you overdid it a bit and thinned your oil too much? You'd better change it right away, just to be safe. Then just ride out the SeaFoam you have in your gas tank. You'll be OK.

Thank you for your indulgence,

BassCliff
 
I've got a bit on my plate for the next few days. When I get a chance, I'll tackle this pup. Every time I've used seafoam in my cars and trucks, it's made a lot of white smoke. I will drain my oil and refill to 2.6qt (that's right for a 650g, right?). I'll keep everybody up to date!

Thanks!
 
I too was intrigued by this post. I picked up a bottle from Pep-Boys yesterday after work. It was about 95 degrees out. Phew. Went home. I have about a 1/2 tank of gas, so a added roughly 2 oz of seafoam to the tank. Drove about 5 miles since. So far, everything seems good. This morning on my startup,choke idle was WAY smoother and I feel quicker of the line. It may be all in my head though.

Question. Since I added to only a 1/2 tank. When I fill-er up, which will prob be soon, should I add a bit more?

If you are just draining from under the engine, it's about 2.6 qts If you also drain from the crank case (which you should, even though I haven't because I totally stripped the bolt :(), it will let out another quart. So your total would be 3.6 qts.
 
drain pan = underside of pan 22mm, where's the crankcase bolt? on the side?
 
Yup, the crank case drain plug is on the side under the crankcase. I had some real difficultly getting if off. Actually, I never got it off. I didn't have enough clearance for a socket wrench. The exhaust was in my way. So I tried using vice grips. Stripped the exposed side of the bolt. That sucker is fused on there! Meanwhile, my underside oil pan threads were stripped from age. So after many attempts at tapping a new oversized drain plug in (thus many oil changes to see if it leaked) I figured I pretty much rotated the oil out of the crank case. So I HOPE!!!:?.


BTW, there is only one fill area.

good luck!!
 
Mr. Euclid,

I thought of something else. SeaFoam, being a solvent, will clean out gunk and sludge in your crankcase. If you have gunk that is actually reinforcing gasket material, and that gunk gets removed, you may develop leaks. I don't know where you are leaking from now, hopefully you might only have to replace an oil pan gasket, if necessary. Leaks are not good. Keep a very watchful eye. Let us know.

Thank you for your indulgence,

BassCliff
 
Fixed it. I changed the oil and, well, turns out there was 6 quarts in this puppy! Holy cow! Everything's running like a champ now, thanks GSR!
